What’s New

Version History

3.60

Jan 16, 2019

• From today, you'll notice a shiny new app button that matches our new logo. You can read more about it, should you wish to, on our blog at SlackHQ.com. Change! Everyone loves it. (Having said that, nothing about Slack or how you use it has changed. Just the button.)

3.59

Jan 7, 2019

What’s New • We now compress jpeg images while uploading them, so image uploads should be quicker and more reliable. If you're happy to sacrifice a little time for a less compressed image, that's fine too: you can toggle this setting in Settings > Advanced.

Bug Fixes • Fixed: When using an external keyboard with an iPad, some keyboard shortcuts were not behaving as they should — or, in fact, at all. They have been brought back in line, and should now function just as you'd expect. • Fixed: You can now use the quick switcher to switch to a DM session with someone no longer on your team. Because people may leave, but knowledge remains. It's a very useful thing that way.

3.58

Dec 11, 2018

Bug Fixes • Fixed: If you have a DM conversation containing only one message, you can, once more, long press to mark that message as unread, and come back to it later. Or not. Up to you. • Fixed: Changing status was proving inconceivably tricky for people whose workspace had customized the list of statuses. Now you can select, deselect, reselect, and customize your status as you wish. • Everything else is fine. (We hope.)

3.57

Nov 26, 2018

What’s New • Need to pause notifications? Thinking of going on vacation for more than 24 hours? Good news. You can pause them beyond a single day, or until a specific date or time. And we’ve also added two new presets to our existing list: “Until tomorrow” and “Until next week”. There! A veritable panoply of new options for pausing notifications! Or, at the very least, "more than before"!

3.56

Nov 5, 2018

What’s New • Now, after you confirm your email, you’ll see a list of your workspaces, and pick which ones you’d like to sign into. And then sign into them!• You can now receive notifications while using the app, so If you're catching up on a channel and you receive a DM you won't miss it (and if that doesn't sound like something you'd want, you'll find this in the notification settings menu).

Bug Fixes • Fixed: Sometimes, using “quick reply” to send a message from a notification would report as “failed to send”, even though it had, in fact, successfully sent. Truth will now prevail.

3.55

Oct 20, 2018

• Fixed: If you received a notification then went to read the channel the notification was from, the Slack icon in top-left of the app would sometimes stay red-dotted until you closed and reopened the app. Even though you had read the message. Even when you were in the channel, reading the message and replying to it. Not always. Not 100% of the time. Just often enough that it confused the heck out of everyone. Sorry about that. It's fixed now.

3.54

Oct 8, 2018

• Fixed: tfw uploading .png images via the share sheet no longer converts them to .jpg format, or any other three-letter collection of letters, like, idk, omg bbq etc. Yay! • Fixed: Users in workspaces requiring single sign-on were unable to use the magic email link, and could only complete the setup process if they chose to "sign in manually". This should be all better now.

3.53

Sep 20, 2018

• On iOS 12, notifications are now grouped by conversation, so all messages from your Slack app come gift-wrapped and packed in handy stacks.

3.52

Sep 10, 2018

• When you set your status, you can now also set a time (or date) for it to expire. No longer will people question how you're "Working remotely on Tuesday" when it's Thursday, or wonder why you've been "At the dentist" for 19 consecutive hours.• Fixed: If someone else changed their status while your app was offline, we would sometimes still show the old status after you came back online. This was confusing for everyone, frankly. Thankfully, it no longer happens.

3.51

Aug 27, 2018

What’s New • Message actions come to iOS: It's now easier to create tasks, comment on tickets, or follow-up on things while on the move. So if you have important tools like Asana, Zendesk and Jira connected to Slack, you can now long press any message and create a follow up without needing to log into those tools. It's very good. We recommend it.• Fixed: A lag in the graphical interface was causing a gap when generating /giphy previews. Going forward, they'll appear in a jiffy, which is a gift, when GIFing. • Fixed: Should you wish to respond to a notification from a channel right from the notification screen (just like in the good old days) you now can, once more.

3.50

Aug 13, 2018

Bug Fixes • Fixed: A layout issue in the "Do Not Disturb" menu was causing gray squares to appear at the top of the settings in that menu. Apologies if you liked them: they're now gone. • Fixed: The notifications preferences for channels were appearing to be the default, even if you'd chosen different notification settings. We were still only sending the notifications you had chosen; it was just the display was wrong. Phew.

3.49

Aug 8, 2018

What’s New • Threads support files — and files support threads. Images and files can now be uploaded directly to threads — you can do it by adding files as you normally would. When you comment on a file, it now appears as a thread reply. And, just like message threads, your file reply stays nested in a thread attached to the file. Finally.

3.48

Jul 17, 2018

What’s New • Move your workspaces around in the Workspace Switcher into the order that makes sense to you, rather than to us. Tap the edit button at the top of that screen, and move them all, using only the power of your finger (on the screen). • And if there's a workspace you no longer need to be in, you can sign out of it from the Workspace Switcher, too.

Bug Fixes • Fixed: Tapping on a channel name will now, once more, highlight the channel name. (It will also still take you to the channel, but that bit wasn't broken).

3.47

Jul 9, 2018

Bug Fixes • Fixed: Large files will now upload better, and succeed more often (or notify you if, for some reason, they don't). • Fixed: The button to show additional attachments was broken, stopping users from being able to see more than 20 attachments in a single message. 20! In a single message! You can do that! (Now!) • Fixed: Users who had selected a non-English language would see an incorrectly-escaped ampersand ("Cosette & Fantine" instead of "Cosette & Fantine")… but only, weirdly, when two users were typing.

3.46.1

Jun 28, 2018

Bug Fixes • We tuned up the engine and gave the interiors a thorough clean. Everything is now running smoothly again.

3.46

Jun 21, 2018

Bug Fixes • Fixed: Editing a message in a thread will now edit the original message, as is right and proper, rather than sending a new one, which was not. • Fixed: When trying to share an image or link to Slack, some people (who were signed in), encountered an erroneous error about being “not signed in”. We will no longer fib about this fact. • Fixed: People a) using Slack in Japanese who wanted to b) send a single word message that c) happened to match the name of an emoji (but was not written with colons like our emoji) were perplexed when we would automatically translate the word into English upon sending it. Technology is weird, friends. We're doing our best.

3.45.1

Jun 6, 2018

What’s New • If you're having trouble with notifications, a new tool (found under Settings -> Notifications -> Troubleshoot Notifications) can help diagnose problems. In fact, opening the tool alone can occasionally fix problems. Which seems like wizardry, but is, in fact, technology.

Bug Fixes • Fixed: Sometimes, opening a notification from a thread would cause older messages in the thread to vanish (paf!) and only the most recent message to appear (ta-da!). A kind of magic, but not a good kind. So we fixed it.• Fixed: Usually-clickable links inside tweets became unclickable when certain apps were set as preferred ones for Twitter links. Now, they're clickable once more.

3.44

May 29, 2018

Bug Fixes • Fixed: It's now, once more, possible to edit comments on images or files.• Fixed: Slack should no longer crash when you're sharing from certain popular news apps. That's all from the team here — and now, the weather.

3.43

May 9, 2018

• Fixed: Videos uploaded from Slack on newer iPhones and iPads now play back seamlessly and correctly (and just as you might have always expected) on the Desktop app.• Fixed: After tapping on a notification to read a message in a thread, the "All Threads" header remained bold, as if there was an unread message. Which there wasn't (or if there was, it wasn't the one you just read, because you just read it). We know. You read it. It all makes sense now.

3.42

Apr 24, 2018

Bug Fixes • Fixed: When replying to a thread and sending your reply to the channel, the text snuggled up with the "number of replies" indicator, muddying the view and muddling everything. It's all clear now. • Fixed: When filtering group conversations, we now also search for people typed after a comma. So if you're looking for that conversation with "Alvin, Simon, Theodore" we won't just return all results for "Alvin". • Fixed: Improved reliability for uploading large videos, from share sheet, and from within Slack.• Fixed: On the German version of the Welcome screen, there were layout issues, because the intersection of language and technology is a beautiful, complex, exciting challenge to deal with. In this one place, and one language, though, it is a problem that has been surmounted. For now.

3.41

Apr 11, 2018

What’s New • Videos can, once more, be saved, by way of the “Open In...” menu item.

Bug Fixes • Fixed: When you tapped on a notification caused by one of your keywords, we weren't highlighting the keyword when you got there. Confusing. These keywords will now be highlighted (highlit?) once more. Better.• Fixed: Channel names were sometimes unreadable on iPads when using the Hoth sidebar theme, due to being white text on a white background. We have eschewed minimalist aesthetic in favor of readability.

3.40

Mar 28, 2018

What’s New • It's now easier to change the name of file uploads, due to a darling little X button that will clear the field so you can rename it.

Bug Fixes • Fixed: When sharing something from Slack to another app via the “Open In...” Button, we'll now preserve the original file name.

3.39

Mar 14, 2018

What’s New • When you share something in Slack, we’ll use the last channel you shared a file as the default destination as is logical. Or at least more logical. • Sending messages in poor connection conditions is now a little more reliable. Because neither snow nor rain nor heat nor dearth of signal should stand between you and us trying to send your message.

Bug Fixes • Fixed: A faulty link that prevented some owners and admins from managing their workspace. • Fixed: Emoji reactions in threads were starting to crowd one another. The gaggle has dispersed and threads should look orderly once again.

3.38

Feb 28, 2018

• Fixed: Two-factor authentication would occasionally become four-, six-, or eight-factor authentication. We’ve fixed this: you’ll now only be asked to authenticate your login once.• Fixed: The option to send replies to a thread back to the channel wasn’t working. You might even say it was stringing you along. We’ve tied up our loose ends and this is now fixed.• Fixed: When testing notifications while using Slack in Japanese, an error message would sometimes appear even if everything was working. Our notifications can now tell right from wrong.

Jan 16, 2019

Version 3.60

• From today, you'll notice a shiny new app button that matches our new logo. You can read more about it, should you wish to, on our blog at SlackHQ.com. Change! Everyone loves it. (Having said that, nothing about Slack or how you use it has changed. Just the button.)

Open. Crash. Open. Crash. DELETES APP!

1. I open slack2. Slack crashes3. I open slack again, slack crashes4. I proceed to tell my boss "sorry, slack apparently doesnt work on an iphone SE not even 2 years old running 10.3.1... and in order to prevent it from crashing I need to upgrade my iPhone (signed their 56 page agreement Los Angeles signing my life away and privacy) then upgrade slack AGAIN" (because "oh it's not working? Have you tried again? And again? Make sure you get in the continuous upgrade and I AGREE cycle, Have you tried rebooting your phone? Yes? Ok try going and getting reborn from scrarch and try again sorry please thank you for choosing slack PLEASE TAKE MORE TIME OUT OF YOUR LIFE FOR US BY TAKING OUR SURVEY!!)... just so I can send a 5 kB message to my boss.... which, apparently cannot send because I am "not online", even though I am able to switch to a call and call out immediately to a friend so I know I have reception (I know I am online). I have cellular turned on for Slack and it still sometimes does not work. Just anither new age crap app. Like anything else created after the internet boom of fake everything where everyone does whatever it takes to transfer money from one person's pocket to their own.

Awesome; does everything it should

I have a love/hate relationship with chat applications, but I think Slack kind of sets the bar for them at this point. The app does basically everything I could ask of it, and it’s quite responsive.

I’ve also noticed lately that there are lots of times I think “man it’d be nice if Slack did ___”, and then before long I open the recently-updated app and that feature appears. (A good example of this, I think, is the way you can now set a status in Slack to expire after a certain amount of time, which is great for something like a ‘working remotely’ status that you want to disappear at the end of the day). This is a tendency that I’ve seen in only a handful of apps/services, and I think it shows a high degree of responsiveness to the needs of their customers, which is awesome.
